Membrane Contactors

March 6, 2012

Membrana-Charlotte recently announced the introduction of the 8 x 40 and 8 x 80-inch Liqui-Cel® Membrane Contactors to its degassing family of products. This new product design uses ASME code-rated reverse osmosis (RO) vessels for contactor housings. The 8 x 40 and 8 x 80 devices are both rated to 300 psi. These devices also utilize combined NPT and Victaulic® connections on the shellside for a stacked system design that reduces the footprint and weight. Both the 8 x 40 and 8 x 80 Membrane Contactors utilize cartridges of polypropylene hollow fiber inside of the RO vessel. An individual 8 x 40 module can process 5.7-28.4 m3/hr (25-125 gpm) and an 8 x 80 can process 11.4-34.1 m3/hr (50-150 gpm). Multiple contactors are piped together to handle higher flow rates. The use of the RO vessels makes system design simple and easy because the vessels are already familiar to operators.
